increased chance of path symmetry for one.
check the ipng thread from 1999 "simple source address selection".
e.g Message-Id: <firstname.lastname@example.org>
if an implementation handles unnumbered links (links without global
addresses) or loopback interfaces then it has to implement the
semi-strong or weak host model. are there router implementation which
implements the strong host model?
